After watching about 20 matches of the World Cup, I realized that these guys could not play any other sport. They are too fragile, too wimpy, too French (except for the African nations). These guys dive and roll around as if a limb had been severed.
I propose that they lace up skates, flood the pitch with water and play on ice with no extra padding. They can wear the shin guards, but still in shorts and jerseys. This would eliminate diving, dangerous kicks and tackling from behind. Hockey players lose teeth, get sticthes and return to the ice. Let's call it sockey and see who headbutts whom.
